Smart Contact Lens Eye-Driven UI Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart contact lenses with embedded displays face limitations in user interface component selection due to anatomical constraints of the human eye, where only a part of the image can be in sharp focus at the center, and peripheral vision is limited, making it difficult to interact with multiple UI components effectively.
Innovation Solution
The system shifts the responsibility of bringing different parts of the image into focus from the eyes to the display by tracking eye movements and correlating them with UI components on the embedded display, allowing selection and activation of UI components without physical gestures, using eye position tracking and processing modules to adjust the image on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image is displayed on the embedded contact lens display, then the UI components are visible to the user, but only a limited portion of the image can be in sharp focus at the center while peripheral vision is blurred
Solution Approach 1:
The patent implements dynamic image shifting on the embedded display that responds to real-time eye movement detection. As the user's eye moves across the display, the image dynamically shifts to maintain the selected UI component in the sharp focus zone. This dynamic adjustment allows the entire image to remain visible while ensuring the active element is always in focus, resolving the contradiction between focus sharpness and visible area.
2Ease of operation
If traditional haptic or gesture-based UI selection is used, then the user can select UI components, but the interaction becomes complex and less intuitive given the anatomical limitations of the eye
Solution Approach 1:
The system uses the eye's natural focusing mechanism and movement as the selection input method. The eye automatically tracks and focuses on UI components of interest, and the system detects these natural eye movements to trigger selection without requiring additional gestures or mechanical interactions. This self-service approach leverages the eye's inherent capabilities, making UI selection intuitive and simple while reducing interaction complexity.
3Measurement precision
If the foveal area is used for detailed vision, then sharp focus is achieved on a small central area, but peripheral vision is limited and cannot provide clear detailed information
Solution Approach 1:
The system dynamically shifts the image on the embedded display based on detected eye movements. When the user's eye moves to bring different portions of the image into the foveal area, the image相应地 shifts to keep the relevant UI components in the sharp focus zone. This allows the user to access detailed information across the entire image area while maintaining high visual acuity through the foveal area's natural capabilities.

AI summary
A smart contact lens system is provided. The contact lens system comprises a contact lens substrate, an embedded display, and an onboard, embedded or off board, remote processor. The embedded display may form a part of the contact lens substrate. The embedded display is configured for outputting variety of UI components to the user. The processor is configured to shift at least a part of an image to a central position of the embedded display to bring the part of the image into focus on the embedded display and select UI component and optionally trigger it; thereby generating appropriate system event. Hence the entire system operation may be controlled with the eye(s).
